10 all w/wm/ it T Z/(Ly concern:

Be it known that I, Cnsnmss a citizen of the United Elts tes, of ll il-ltinshurg, in the county and State oi lennsylx this, have i new and useful lniproveznen t i i Coil Supports, oi Wl'llfjll the iollcwing; specification.

My inventionrelatos to electrical transformers and has special re for supporting the coils of tr: shell type, in. Wl'iich laini. shell assembled cl? The object of my inventio former, independent 3" or shell, that slit l I 1 struction and ed, effectually maintain the shape and ge positions of the cells under in .fiilil-lli. eleotro-ma' netic stre' The coils of shell e transformers. heretofore constructed, have sometimes he come distorted or displaced when snlyieoted to excessive currents i reason ol short-circuits in the Windingv (1i across the line sup plied therei'rom, since they were supported directly upon their laminated cores, which coilld not be made suil licicntly rigid to prevent such distortion. A. distortion of this nature may materially damage the transformer since the coil insulation is usu ally cestroyed and the voltage ratio rendered inaccurate.

The coil support of my invention provides for the eilective maintenance oi the coil lotions and the shape and insulation oi the Winding under adverse conditions, and con1- prises a pluralitv of beams, which are th .st through the coils and which are found sport and against the opposite interior surface of the assembled coils by separating rods. The beams are of sufficient length to llon" the sepsratii'ig rods to be located ncnr llltll' ends Without interfering with the lnniirnied core itllil also to allow the assembled cofs to he supported by the frame from il hollow core lmse.

A rigid supporting frame is thus provided which is entirely 5 independent of any settling or Warping ol' the more 2 and which s capable of withstsruling any tendency on the part of the coil to becon distorted or to move out of place. El hu, ng llloclis or plat-es ll) lid Y3 oi wood. or othhr insulating material, they prefers outer surfzuzes ol' the T-beams, in order that the coils may not be short circuited when pressure is applied.

Each of the beams 6 and 7 comprises a flatbase which engages the inner surfaces of the coils and a central, longitudinal web l l *hich is substantially perpendicular to the base.

The beam 6 is provided with a hollow boss 15 at each cnd,-through which the separating rods project, and the beam 7 is similarly supplied, except that the hollow boss 16 at one end is detachable so that it may more readily be inserted between the assembled laminae and the winding. The detachable boss 16, which illustrated in Figs. 6 and 7, is provided with a suitable notch 17 that engages the web 14 on the beam 7 and with a base 1.8 which is clamped to the base 15 near its extrcmity,

The transformer may be provided, in the usual mainjier, with a containing tankor .l'iousing 2!. which may be filled with oil or o ther suitable insulating fluid.

' although I have shown and described a specific coil support comprising single pair of beams and separating rods, I. desire that my invention shall not be restricted to such an arrangement,

but that any suitable means for accomplishing the same result in connection with any well known type of transformer shall be included within its scope.

I claim as m invention:

it An' extc siblc frame for supporting transl'rn'mcr coils that comprises a plurality of supporting beams and separating rods therefor.

transformer coils that comprises an upper and. a lo er supporting beam and a plurality of rods which engage said beams near their ends.

In transformer, the combination with a magnt-ilizablc shell or core and a winding therefor, of means for supporting said winding independently of said shell or c'ore.

I. In a transhn'mcr, the combination with a magnetizaliile shell or core, a winding and a supporting base therefor, of means for supporting said winding from said core base independently of said shell or core.

5. {n a transformer, the combination with a inagnolizablc shell or core and a winding therefor, of an extensible frame for support ing said winding independently of said shell that comprises a plurality of supporting beams and separating rods therefor.

6. In a transformer, the combination with a magnetizable core and 5. winding therefor, of an extensible frame for supporting said winding independently of said core that is opening in said assembled c.1111 oxtm'isiblc frame for supporting placed within the assembled coils of said winding and extends be ond said coils.

7. In a transformer, the combination with a magnetizable shell or core, a winding and a .supporting base therefor, of an extensible .frame for supporting said winding independently of said shell or core that is placed with in the assembled coils of said winding and is supported by said core base.

8. In a transformer, the combination with. a magnetizable shell or core, a winding and a supporting base therefor, of an extensible frame for supporting said winding independently of said shell that comprises an upper beam which engages the upper surface of the winding, a lower beam that rests on said core-s11pporliing base, and a plurality of separating rods which f orce said upper and lower beams apart.

9. In a transformer, the combination with a winding comprising a plurality of coils, of means for maintaining the relative positions of said coils.

10. In a transformer, the combination with a magnctizable core and a winding therefor comprising a plurality of coils, of means for supporting said winding independently of said core and for n'iaintaining the relative positions of the coils.

11. In a tr msformcr, the combination with a winding comprising a plurality of coils, of an extensible frame for maintaining the relative positions of said coils.

12. In a transformer, the combination with a n'iagnolizablc core and a winding therefor comprising a plurality of coils, of an extensible frame for sup porting said winding independently of said core and for maintaining the relative positions of said coils.

13. In a lransfm-mer, the combination with a winding comprising plurality of coils, of an extensible frame for n'iaintaining the relative positions of said coils that comprises a plurality of supporting beams and separating rods therefor.

14. In a transformer, the combination with a magnctizable core and a winding therefor comprisingn plurality of coils, of an extensible frame for supporting said winding indc pendently of said core and for maintaining the relative positions of said coils that comprises a plurality of supporting beams and separating rods therefor.

In testimony whereof, I have l'iercunto subscribed my name this 7th day of September 1905.
